New breakthroughs in pad printer technology

The development of printing machines toward automation should be the consensus in the industry. This is the fundamental way to increase production efficiency and reduce costs. It is also an inevitable requirement for the shift of printing technology from labor-intensive industries to technology-intensive industries.

At present, the high degree of automation of the printing machine is more common is the rotary transfer printing machine, in the printing process is completely automatic, but the process of placing the workpiece and removing the workpiece still rely on manual. The degree of automation is affected. The vast majority of manufacturing companies still have imperfections in their consideration of the quality issues that arise during the printing process. Even such a printing machine must face many challenges if it is to achieve true automated printing.

The universal automatic pad printer core tube is relatively rare, but there are many surprises for a fully automatic pad printing machine targeting a specific product. For example, a full-automatic printing machine for printing CDs and a full-automatic printing machine for printing bottle caps. The automation of the pad printing machine essentially means the automation of the product delivery, and there is little change in the pad printing part. Various new technologies and information have broadened our horizons. The infiltration of other printing technologies has given us new inspiration. The interviews of customers have led us to become passionate about the realities of the automation of printing machines. The following text may not represent the direction of the development of the pad printer, but can you reject it fresh breath?

Web printing machine

There are two types of paper feeding methods for any printing process: one is sheet-fed and the other is web. The only machine that does not print web in the pad printing process. As mentioned above, pad printing technology is the only technology that does not integrate with paper printing. If the printing process does not have an advantage in terms of paper, I think it should be mainly attributed to the fact that the paper format is very large. A type of printing pad printing process like conventional sticker paper may not be a dream. It has no technical problems in printing paper and paper. Its printing area is very small. Compared with resin-type adhesive printing presses, it is less difficult to manufacture, it is more convenient to operate, and the price of the machine is lower. From a technical point of view, since screen printing can be used for web printing, there is no problem with pad printing on webs. Through our understanding, some manufacturers are working on the development of monochrome web printing machines. It is estimated that prototypes will be available within one year. Printing machine with cleaning device

Japan first installed a plastic head cleaning device on the pad printing machine to improve the printing quality. In the printing process, since the ink on the surface of the plastic head cannot be completely transferred to the printed matter, the residual ink of the resin will gradually change the edge of the graphic trace on the surface of the plastic head, causing the sharpness to decrease. There are two ways to solve this problem: one is to improve the deinking ability of the plastic head; the other is to install plastic head cleaning device. The features of the plastic head cleaning device are: In the process of retreating the printing plastic head, one more printing action is performed on the adhesive paper than the ordinary printing machine, and the residual ink on the surface is removed.

For multi-color printing, the improvement of overprint accuracy is obvious with the addition of cleaning devices. If multi-color printing involves dot duplication, the phenomenon of dot gain will be significantly curbed. At present, the domestic printing machine has not appeared in the trend of adding plastic head cleaning devices. It may be related to our understanding of the printing technology. We always think that: printing is not a very fine printing technology, and it does not need to be over-printed. The details of the process.

Accurate multi-color pad printing machine

The traditional rotary printing machine has higher production efficiency, but the accuracy of overprinting is worse, not to mention that fine dot printing cannot be completed, and it is not easy to require slightly higher color pad overprinting. This is related to its own structural defects. In 2003, a Japanese printing machine manufacturing company took the lead in introducing a new four-color pad printing machine. This multi-color pad printing machine has a very different form of movement than a traditional multi-color pad printing machine; it is rotated around a central axis. Four groups of plastic head systems constitute a printing device, each printing is rotated by 90°; the ink supply device is constituted by four groups of printing plates rotating around another rotating center, and each printing head also rotates by 90°, and each group of plastic heads is only fixed The printing plate contact, overprint is very accurate. as the picture shows. The pad printing machine uses two precise rotating cylinders to control the rotation of the rubber head system and the printing plate system respectively. The structure is compact, the movement is coordinated, and there are almost no components machined, so the overprinting effect is very good.

Many craft gifts need careful printing. If overprinting is inaccurate, it will inevitably affect the value of the product itself. Developing an overprinting printing machine does not seem to be an optional matter. If we do not have a better design idea for the time being, it may be Learn from the above examples.

The fact that the threshold of pad printing technology is too low has caused the proliferation of pad printing technology. The printing companies face fierce market competition and the profit space is constantly being compressed. How to maintain a strong position in this competition requires the thinking of people in the industry. Domestic printing companies generally suffer from the problem of poor innovation capability. This is caused by the fact that China's market economic system has not been perfect for a long time and is not cruel. It is also a fatal malady that the Chinese economy has been obscuring at high speed. We believe that only those companies with strong innovation capabilities can truly lead the Chinese printing industry to face new challenges. Innovation is our weapon to overcome all difficulties. Only innovation can make us stand forever and become the winner of the last laugh.
